数据

[
  {
    title: '市值',
    prop: 'sz',
    titleData: [
      {
        title: '市值',
        label: '市值',
        prop: 'sz',
        isShow: false,
        fixed: false,
        width: 100,

        prop: 'ccsz',
        isShow: false,
        fixed: false,
        width: 120,
        align: 'left'
      }
    ]
  },
  {
    title: '持仓',
    prop: 'cc',
    titleData: [
      {
        title: '资金费率',
        label: '资金费率',
        prop: 'avgFundingRateByOi',
        isShow: false,
        fixed: false,
        width: 100,
        align: 'left'
      },
      {
        title: '持仓',
        label: '持仓',
        prop: 'openInterest',
        isShow: false,
        fixed: false,
        width: 100,

[{
        title: '持仓',
        label: '持仓',
        prop: 'openInterest',
        fixed: false,
        width: 100,
        isShow: true,
        align: 'left'
      },
      {
        title: '持仓变化(24h)',
        label: '持仓(24h%)',
        prop: 'h24OiChangePercent',
        fixed: false,
        width: 100,
        isShow: true,
        align: 'left'
      },
      {
        title: '多(4小时)',
        label: '多(4h)',
        prop: 'h4LongVolUsd',
        fixed: false,
        width: 100,
        isShow: true,
        align: 'left'
      }]

实现

data.forEach(item => {
  item.titleData.forEach(titleItem => {
    const match = newData.find(newItem => newItem.prop === titleItem.prop);
    if (match) {
      Object.assign(titleItem, match);
    }
  });
});

const data = [
  {
    label: "收藏",
    prop: "sc",
    fixed: true,
    width: 60,
    isShow: true,
    align: "center"
  },
  {
    label: "排名",
    prop: "pm",
    fixed: true,
    width: 60,
    isShow: true,
    align: "center"
  },
  {
    label: "币种",
    prop: "symbol",
    fixed: true,
    width: 90,
    isShow: true,
    align: "left"
  },
  {
    label: "价格",
    prop: "price",
    fixed: false,
    width: 100,
    isShow: true,
    align: "left"
  },
  {
    title: "价格变化(24h)",
    label: "价格(24h%)",
    prop: "h24PriceChangePercent",
    fixed: false,
    width: 100,
    isShow: true,
    align: "left"
  }
];

const newData = [
  {
    title: '持仓',
    label: '持仓',
    prop: 'openInterest',
    fixed: false,
    width: 100,
    isShow: true,
    align: 'left'
  },
  {
    title: '持仓变化(24h)',
    label: '持仓(24h%)',
    prop: 'h24OiChangePercent',
    fixed: false,
    width: 100,
    isShow: false,
    align: 'left'
  },
  {
    title: '多(4小时)',
    label: '多(4h)',
    prop: 'h4LongVolUsd',
    fixed: false,
    width: 100,
    isShow: true,
    align: 'left'
  }
];

使用

newData.forEach(newItem => {
  const matchIndex = data.findIndex(item => item.prop === newItem.prop);
  if (matchIndex !== -1) {
    if (newItem.isShow) {
      data[matchIndex].isShow = true;
    } else {
      data.splice(matchIndex, 1);
    }
  } else {
    data.push(newItem);
  }
});

console.log(data);
